Summary
In this chapter, we learned about some advanced data modeling techniques, as well as how to implement aggregations using big data in Power BI. We also learned how to configure incremental refresh, which also helps deal with the challenges of working with large data sources. Then, we looked at the concept of Parent-Child hierarchies and implemented one in Power BI Desktop. After that, we learned how to deal with roleplaying dimensions in Power BI. Last but not least, we implemented calculation groups.
In the next chapter, Row-Level Security, we will discuss a crucial part of data modeling that is essential for organizations that believe the right people must access the right data in the right way. See you there!
